SNPN-Enabled UE Parameters for Dynamic URSP and PS_Data_Off Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for UE accessing Stand-alone Non-Public Networks (SNPNs) using credentials from a credential holder do not adequately handle UE Route Selection Policy (URSP) and 3GPP PS_Data_Off exempt services, leading to inefficiencies in parameter usage.
Innovation Solution
A UE is configured with a list of subscriber data containing SNPN selection parameters, allowing it to select an SNPN based on these parameters and apply different URSP and 3GPP PS_Data_Off exempt services upon successful registration, distinct from pre-configured settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UE uses pre-configured URSP and 3GPP PS_Data_Off exempt services from the subscribed network, then the authentication process is simplified, but the UE cannot dynamically adapt to different SNPNs
Solution Approach 1:
The patent segments the URSP and PS_Data_Off exempt services parameters by SNPN identity. Instead of using a single set of pre-configured parameters, the UE maintains separate parameter sets for each SNPN, allowing dynamic selection and application of appropriate parameters based on the target network while managing complexity through structured organization.
Solution Approach 2:
The patent introduces dynamic parameter selection where the UE can switch between different URSP and PS_Data_Off exempt services configurations based on the selected SNPN. This dynamic adaptation allows the UE to optimize its behavior for each specific network while maintaining the ability to access multiple networks.
2Reliability
If the UE applies different URSP and 3GPP PS_Data_Off exempt services for each SNPN, then network parameter handling is optimized, but the configuration management becomes more complex
Solution Approach 1:
The patent organizes configuration data into distinct segments associated with each SNPN identity. The URSP and PS_Data_Off exempt services are separated into individual configurations that can be independently managed and applied, reducing the complexity of managing a single monolithic configuration while ensuring reliable network-specific parameter handling.
Solution Approach 2:
The patent applies local quality by tailoring specific URSP and PS_Data_Off exempt services parameters to each SNPN's requirements. Each network receives customized parameters optimized for its specific needs, improving reliability while the modular structure keeps management complexity manageable through localized configuration rather than global reconfiguration.

AI summary
A method of handling parameters of a subscribed network upon accessing a selected Stand-alone Non-Public Network (SNPN) using credentials from a credential holder is proposed. The UE selects an SNPN using a configured list of subscriber data, e.g., based on SNPN selection parameters contained in a selected entry of the list of subscriber data, or selects the SNPN based on SNPN selection parameters associated with a PLMN subscription of a USIM card. The UE accesses the selected SNPN using credentials supplied by a subscribed network, which is identified by the selected entry or by the USIM card. Upon successful registration to the selected SNPN, the UE applies a list of 3GPP PS_Data_Off exempt services that is different from a configured list of 3GPP PS_Data_Off exempt services associated with the selected entry, and evaluates a URSP that is different from the pre-configured URSP of the subscribed network.
